NAS is forcibly encrypted though NEA = NULL #324

Hi, Herle and guys. Here is a pcap that was caught on N2. I noticed an odd phenomenon. NAS was forcibly encrypted though the network and UE both acknowledge that the NEA = NULL in the SMC signaling (Packet 62) But NAS began encryption after that from packet 64

Could you please tell me what's going on ?

Finally found the resolution.
